Specification of Letters Patent. Patentgd A 14 1914p A Application filed October 1, 1912. Serial No. 723,387.

To all whom it may concern Be it known that I, CHARLES Swmnow- SKY, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented new and useful Improvements in Pencil Attachments, of

which the following is a specification.

The general object of this invention is the practical embodiment being shown in the accompanying drawing, wherein Figure 1 is a side elevation of a pencil,

showing the attachment applied thereto and.

constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view.

Referring more particularly to the accompanying drawing in which like reference characters designate similar parts, 5 indi catesa pencil of any well known form and having a portion thereof preferably. provided with indelible lead 6.

In order to directly protect the pencil 5, there is provided an inner elongated ferrule 7 which is preferably cylindrical in cross section, the same being made of resilient metal and split as indicated at 8 whereby it may he slipped over either end of the pencil and be securely retained in position. A rubber or eraser 9 of the usual forfnis secured in the free end of the ferrule in any preferred manner. An outer tube or ferrule 10, also cylindrical in cross section and of a slightly larger diameter than the inner ferrule 7 is adapted to be slipped over the last named ferrule in order to incase the eraser and protect the same. The inner end of the tube 10 is provided with a roughened or sanded portion 11 which engages the said eraser 9, whereby upon turning the said tube it will be seen that any dirt that may have accumulated upon the eraser will be removed by the said roughened portion, thus insuring a clean eraser whenever desired and preventmg the paper from becoming unnecessarily solled. When it is desired to use the pencil for writing both the inner ferrule 7 and the tube 10 may be removed from engagement with the pointed end of the pencil and slipped over the other end thereof.

. From the foregoing description taken in connection with the accompanying drawing, it Wlll be seen that the invent-ion contemplates providing a device which is simple in construction thus reducing the cost of manufacture of the same to a minimum, and which is durable and effective in carrying out the purpose for which it is designed.

What is claimed is i A pencil attachment including a ferrule formed at one end to engage the pencil, an eraser secured in and projecting beyond the opposite end of the ferrule and a tube havinga closed end and an open end to be passed over the eraser carrying end of the ferrule, the interior surface of the tube being pro vided with a roughened or sanded portion to cooperate with that surface of the eraser projecting beyond the ferrule, the tube being adapted for rotative movement upon the ferrule to cause the roughened or sanded surface of said tube to have an abrading effect upon the projecting surface of the eraser. I

In testimony whereof I aflix my signature in presence of two witnesses.
